Abstract
Description
-
- the (amount of) reactive power compensation required in the energy saver mode may be a setting that can be modified according to customer's needs; the reactive power compensation may then be constant and may try to match this predetermined setting; and/or
- the (amount of) reactive power compensation required in the energy saver mode may be determined depending on the reactive power drawn by the load and/or the UPS system itself, the reactive power on the UPS input, and/or the power factor of the UPS system in the energy saver mode; and
- the maximum reactive power compensation that can be achieved by one power module (maximum compensation per power module).
number of active power modules=reactive power compensation/maximum compensation per power module
